SPINDLE.

Application filedluly 6,1921.v Serial No. 482,738.'

To-ctZZ whomztmcty concern: I l g p Be it known `that I', CHAnLEsA. InoULx,

a citizen of the United States, residing atlVoonsoclret, in the `County of `Providence and State ofRhode Island, have invented new and useful Improvements in Spindles, 'of which the following is va specication.

My present invention pertains to spindles such for instance as are employed to support a bobbin or other yarn holding device `on spinning machines and thelike, in whichl the spindle remains stationary and the bobbin rotates about the same incident to the unwinding of the yarn from the bobbin.

The object of the invention is not only to centralize the spool or bobbin aboutfthe supporting spindle with but a slight amount of friction, but to overcome the objection of the lyings of the yarn from clogging under the base of the spindle and thereby prevent rotation of the bobbin. v The invention in all of its details will be fully understood from the following jdescription and claims, when the same are read in connection with the drawings,` accompanying and forming part of this specification, in which:

Figure l is a side elevation of the spindle and bobbin as properly positioned thereon.

Figure 2 is a longitudinal sectional View of the spindle;y v

Figure 3 is a slight modification of ythe spindle construction shown in Figures 1 and 2.

Similar numerals of reference designate corresponding parts in Figures land 2 of the drawings,iwhich figures I will describeI iirst.

The stationary spindle l is slightly `decreased in diameter at its lower end as indicated by 2 and the said lower end 2 is adapted to seat on the' opening of the board orrame 3 as illustrated.

Secured to and adapted to remain fixed with respect to the spindle is the base portion 5 that is provided with the integral collar portion 4, and surrounding the base 5 and also a portion of the spindle 1 and adapted to revolve with respect to the base and spindle is the casing 7 The base 5 is so constructed at its upper end that a ball race is provided for the bearings 6 between the casing "1'.Y

At its upper end the spindle is provided with a member 9 that is decreased in size at itslower end 10 whereby it may-be forced into the `upper end; of the spindle,

to yseat between the shoulder' at the lowerV surface 'of the member- 39 and the upper end of the-spindle is a ring Thisring isv adapte t for the purpose of kdiminishing friction. bef tween the bobbin ll andthe spindle and as will be manifest the said ring is adapted to revolve with respect to the spindle,'and` hence the bobbin times.

At this point I `would haveit understood that I do not wish to confine myself to the exact construction of member 9 as said member may be constructed in any manner which fairly falls within thescope of my claims, as its sole purpose is to confine the ring 8 on the vspindle l.

In Figure 3 I have shown the modified form of construction of the the collar la and thel r'evoluble member 7a together with the bearings 6a. The construcwill lbe centralized. at all tion is practically ther same as that shown in Figures l and V2, with the exception that the top of the base 5a is of a slightly dierent configuration.l

Because ofthe construction of the device base 5a having distinctly the base portion is lifted slightly above the board 3 andhence the liability of flyings from the yarn gathering under the base and the :board'to the extent that 'said flyings impede the `proper rotation of the bobbinV is effectually precluded, and the stopping vof the bobbin 4orl the breaking of the yarn from such cause is practically overcome.

The construction will also assure the even retention of the bobbin in one positionk with respect to the spindle l, and due to the construction of the ring 8 and casing 7 all friction will be -removed between the spindlev and bobbin. i, y

Thev device illustrated and described is 4simple in construction and comprises no delicate parts such as are liable to become inoperative "after a short period of use and many of the disadvantages attributable to spindles nowin use.y Having described my invention, what I claim and desire to secure `by *Letters-Pat! ent, is

the lconstruction will obviously overcome f l. In'adevice for the purposeset forth,

the combination of a spindle slightly ,de-

creased in diameter at its' lower'end, a cas- .ing surrounding the spindle and secured thereto, a ferrule mounted in the upper end of the spindle, a ring arranged on the spindle ranged in the Casing and having an integral collar whereby the spindle is elevated and 'anti-friction means arranged between the core and casing; said easing being so con-Vv strueted and arranged to prevent foreign matter from gaining access to the anti-friction means.

2. In means for the purpose set forth, the combination' of a spindle, a ring arranged on one end of the spindle, a'casing secured to the opposite end or' the spindle', a revolnble member arranged Within the casing and having a lower depending portion for elevating the spindle, and anti-friction means interposed between the casing and revoluble member and adapted to prevent yarn from impeding rotation of the revolnble member.

spindle, and having an integral portion 'for' 'elevating the spindle, anti-friction means interposed between the revoluble memberv and the spindle and means arranged on the upper end of the spindle .for centering a bobbin thereon.

ln testimony whereof have hereunto set my hand in presence of tWo subscribing Wit-y nesses.
